Notobryon wardi, the iridescent nudibranch, is a species of scyllid nudibranch, and is found in South Africa. It is a marine gastropod mollusc in the family Scyllaeidae.[1]
This species is found around the South African coast from Elands Bay to Jeffreys Bay. It is usually found inter-tidally but has been found to 20 m.[2]
Notobryon wardi is a medium-sized (up to 50 mm) smooth-bodied nudibranch. The body is reddish-brown with iridescent blue-green spots on its sides and back. The smooth rhinophores are surrounded by cup-like sheaths. Two sets of wispy gills are flanked by flattened lobes extending from the body.[3]
Notobryon wardi feeds on hydroids. It can swim when disturbed using lateral movements of its body.
